A wave is travelling along X-axis. The disturbance at x=0 and t=0 is `A//2` and is increasing. Where A is amplitute of the wave. If `y=A sin(kx-omegat+emptyset)`, deetemine the initial phase `empyset`.A. `(pi)/(6)`B. `(5 pi)/(6)`C. `(pi)/(3)`D. `(11 pi)/(6)` |

Answer» Correct Answer - B At `t = 0, x = 0` `(A)/(2) = A sin phi rArr phi = (pi)/(6), (5pi)/(6)` since, `(dy)/(dt)` is positive for `phi = (5pi)/(6)` |
